Abstract:Currently, the main task of the researches on impacts of ozone on crops is how to build effective models. These models are used to evaluate and forecast the loss of crop yields and agriculture caused by ozone. The researches on models of the impacts of ozone on crops in recent years are introduced. The models can be divided into three types: statistical models, photochemical models and mechanism models. In order to overcome the limitation of the existing models, the future models of ozone impacts on crops should be modularized and general and the comprehensive models will be established. At last, the development trends of the related studies in China are discussed.
